457.2 cm

Explanation:

Using ratios. Note that a ratio when written this way is not the samething as a fraction. It is comparing the count of the top number to the
count of the bottom number.

In a fraction the bottom number is used as an indicator of size, not a count

Using the conversion of 1 inch is approximately 2.54 cm

Write this as: 2.54 cm1 inch

'..............................................................................................................

1 foot has 12 inches so to see how many centimetres there are in 1 foot we need to change the 1 inch in 2.541 into 12 inches. So we need 12 lots of 2.541.

What we do to the bottom we do to the top

Multiply by 1 but in the form of 1=1212

2.541×1 2.54×121×12 = 30.4812

So 30.48 is the number of centimetres in 12 inches (1 foot)

'...................................................................................................................

But we need 15 feet so we need 15 lots of 30.4812

Multiply by 1 but in the form of 1=1515

30.4812×1 30.4812×1515 = 457.2 cm180 inches

where 180 inches is the same length as 15 feet

So 457.2 is the number of centimetres in 180 inches (15 feet)
